GAS-REGULATO R.

SPECIFICATION forming part of Letters Patent No. 340,112, dated April20, 1896.

Application filed January 1R, 1886. Serial No. 188,962.

To all whom, it may concern.-

Be it known that I, HENRY H. GRIDLEY, a citizen of the United States,residing at Holyoke, in the county of Hampden and State ofMassachusetts, have invented new and useful Improvements inGas-Regulators, of which the following is a specification.

This invention relates to improvements in gas-regulators; and theinvention consists'in the peculiar construction and arrangement ofparts, as hereinafter fully described, and pointed outin the claims, theobject being to simplify and reduce the number of the parts in suchmachines, whereby their efficiency is increased and the necessity offrequent repairs is obviated.

In the drawings forming part of this specitication, Figure 1 illustratesin a vertical sectional view a gas-governor embodying my irnprovements.Fig. 2 is a transif'erse section of the valve-case. Fig. 3 is atransverse section of the valve-cage and the valve-spindle above thevalve in Fig. 1, showing the upper end of the latter in plan view.

In the drawings, h is thc valve-case, having a screw-threadedinlet-opening at its lower end and a like outlet-opening inits side. Theordinary gas-conducting pipes are attached to the regulator at saidopenings,the service-pipe to said inlet, and that which supplies gas tothe burners to the outlet. The upper end of the valve-ease isscrew-threaded to receive the nut K,having a central opening through it,as shown, and at the lower end of said serewthread is an annular seat,18. y

The valve-case has cast in itthe hollow cage-receiver n, ofsubstantially rectangular form in cross-section, whose upper wall hasone end united to the side of said ease, and its lower wall is united tothe upturned edge of the diaphragm m, which extendsin a horizontaldirection across the case 7e, just above the inlet of the latter, andbetween the said up turned end of said diaphragm and th adjoining innerside of the case h is thereby formed a gas-passage, z, through which gasflows from the said inlet-opening to the interior of the cage-receivern. The upper and lower walls ofthe latter are provided with circularperforations to receive the valve-cage e,and circular (No model.)

seats 16 and 17 for the anges on the valvecage, as below described. Saidvalve-cage consists of a head, 13, having a flange formed around itsborder, which is seated on said seat 18 of the ease lz., and from itprojects upwardly the tubular stein c', and attached to its under sideare the downhanging legs 6 (i 6 6, having the laterally-prejectingflanges 7 and 9 surrounding them, said flanges being Seated on the uppersides of said upper and lower walls of' the cage-receiver a. Said legs 6(shown in cross-section in Fig. 3) extend through said lower wall ofthereceiver 11, and form between their inner edges a guide for the lowerend, 3, of the doubleheaded valve o, the lower seat for the latterheilig formed at 5, between said legs, and the seat for the upper end,2,0f said valve being formed at 4, also between thelegs G. The upperend, 2, of said valve o is made of less diameter than its lower end, inorder that said upper end may be passed through the opening surroundedby the valve-seat 5, to place it within the cage. The gas-passages, asindicated by the arrows in Fig. 1, are between the legs 6 at 12. Aglycerine-eup, b,eontainingasuitable quantity ot'glycerine,f, issoldered or otherwise suit ably secured to the upper end ot the saidtubular stem e', and that portion of the bottom ot' the cup b directlyover the center of said stem is perforated to let the valvespindle dpass freely therethrough, and surrounding said central perforation are aseries of other perforatious, fi, sufficient in number to form in theaggregate an unobstructed gasway for the free passage of gas through thestem einto theinverted-cup-shaped gas-holder a, and vice versa. Saidgas-holder a is secured to the upper end of the spindle d by the nuts a'af, and the lower edge of the holder dips into the glyeerinef, as shown,thereby sealing the gasholder in the usual manner. The valve o isattached to the lower end of the spindle d, as shown, the latterextending from the apex of the gas-holder through a portion of thebottom of the glyeerinecup and the stem e to within the valvecage e. Thebot-tom of' the glycerine-eup b is elevated above the level of theglyceriue f, in order to provide a gas-inlet therein throughperforations fi, without pro ICO ' tween said flanges and seats, and thenut' K being` screwed against the head 13, all; of said beari iig-facesare brought closely together, an d gas-tight joints are formed betweenthem. The course of the gas entering the said inlet to the caseh is asindicated by the arrows in Fig. l, and the gas enters the open end ofthereceiver n, passes between the legs .6 ofthe valve-cage, and thence upand down through the valve seat openings therein, passing between saidlegs, between the head 13 and {iange 7,and under the receiver n to theoutlet of the case h. The gas freely passes up the stem e into thegas-holder a, and the variations of Apressure either in the supply or byreason of the consumption of more or less gas causes a. movement ot' thegas'holder up and down, and a consequent movement of the valve o towardand from its seats, thereby restricting the gaspassages between thelatter and the valve 'when there is an excess of pressure, andincreasing the size of said passages when the pressure is low, therebyregulating the quantity of gas which may pass through the niarhine, sothat there is little, if any, variation thereof under differentpressures', the burners being the saine under said varying conditions.

VVhat I claim as my invention is- 1. A gas-regulator consisting of. thefollowing elements, viz: a valve-case, h, having the requisite inlet andoutlet openings and ascrewthreaded opening in its upper side, throughwhich the valve-cage is introduced, and having ahollow cagereceiver, n,formed therein, one end of which is open to receive gas, and whose upperand lower walls are perforated to receive the valve-cage, combined witha valve-cage, e, having side openings and valveseats therein and angesthereon to -bear on said walls of the receiver, and having the head 13,provided with the tubular stein e,the nut K, the double-headed valve o,the gasholder a, the valve-spindle d, connecting the latter and saidvalve, and-the glycerine-cup bp,

permanently attached to the upper end of said hollow stem, substantiallyas set forth.

2. The val ve-case h, having the hollowcagereceiver n therein, thevalve-cage e, passing vertically through said receiver and provided withtwo valve-seats and the hollow stem e',

the nut K, securing said cage to the case hand d to said receiver, thedouble-headed valve o, the'gas-holder a,the spindle d, passing throughsaid stem and' connected to the said holder and valve, and theglycerine-cup b, permanently attached to said hollow stem, combined andoperating substantially as set forth.
